Is wireless mouse really bad in gaming?

i got Logitech G5,G7 and G9 with me
but i dont really can feel that lagness of the wireless lo,that's why i said,is wireless really that bad?
anyway,Mamba also running 2.4GHz RF right?

Yup,i got MX518 too but i've sold it to forumer hilmingah.
As u can see,my mouse all got one same point,can add weighter
i like heavy mouse a lot,i put all the heaviest weighter inside my mouse.
MX518 has same design with G5,but i cna tell,G5 is better cause it's heavier and it has laser engine instead of optical,but it makes no difference for me,cant really feel it.but MX518 has one more button to program which is the "document flip" button,G5 it has no the button that i mentioned.

so,simple conclusion:

MX518:
Optical,smooth palm surface,additional document flip button (programmable to other function)

G5:
Additional weight,Laser,rough palm surface.

G7:
Laser,Wireless,no weighter but the battery is heavy,lack of additional document flip button and lack of one side button.

G9:
Laser,smaller,but the weighter cant put as many as G5,not so comfort to hold compared to G5

as for mouse pad,i prefer rougher surface one better control,and it has to be big enough

mamba using RF only right?
RM500 mouse using RF is a bit no worth lo
but is RF really that suck? i know it can use in short distance only.

deciding whether G9x or Kone to replace my current X8 Sidewinder, which one to go? budget unlimited

Diamond
i ask my boyfriend to buy for me when he wanna marry me


it's not my taste for now

if u put this mouse on my table, i also wont know that it costs me 14k pound. and straight i will use ti for gaming purpose and terus slam the mouse when i pawned by ppl

selling my Sidewinder X8 too
going to go for mamba
